Boil the gunk from the inside of the squash for 3-5 minutes to make it easier to separate the seeds. Once the seeds are cleaned, pat dry and place in a bowl with oil and spices. Mix until more or less evenly coated, then spread on a pan and bake at 350F/180C, until they’re browned or you hear the first pop. If they start popping, take them out of the oven! Serve once cooled.
